Abstract (en)
[origin: EP3266508A1] A ballast water production method includes a filtering step of passing raw water supplied into a housing (20) through a filter (21) from a primary side that is upstream of the filter (21) to a secondary side that is downstream of the filter; a volume-increasing step of, after the filtering step, increasing a volume of water present in a space on the secondary side of the housing (20) while the supply of the raw water into the housing (20) is stopped; a pressurizing step of, after the volume-increasing step, pressurizing an inside of the housing (20) from the secondary side while the supply of the raw water into the housing (20) is stopped; and a rinsing step of, after the pressurizing step, passing a fluid through the filter (21) from the secondary side to the primary side while the supply of the raw water into the housing (20) is stopped.
